A small plastic tank to use for a photo tank might be a good investment. Then if you cut a piece of clear acrylic from Home Depot to just fit inside, you can gently squeeze the fish in the water against the front of the tank. This will allow the forum members who are particularly good at fish ID's to be able to see the more of the traits of the smaller and more difficult to identify species.
Sounds good, I actually have a small tank like that, I will take it out from now on, thanks.
